Mike Huckabee and Mitt Romney are closing a gap with President Barack Obama, according to a new poll out Wednesday.

Obama has just a one-point lead over Romney, with 46 percent of the vote in a Marist College survey, down from a 13-point lead in January.

In a hypothetical matchup with Huckabee, Obama has a five-point lead, taking 48 percent of the vote to Huckabee's 43 percent. In January, Obama led the former Arkansas governor by 12 points.

Among Republicans and Republican-leaning independents surveyed, Romney leads the primary pack with 18 percent of the vote, beating Huckabee by one point.

Donald Trump comes in third with 13 percent of the vote, followed by Rudy Giuliani with nine percent.

Eleven percent of Republican and Republican leaning voters surveyed by Marist said they were undecided.

The national survey of 1,274 adults was taken April 10-14 and has a margin of error of plus or minus three percentage points. The margin of error for the subset of 468 Republican and Republican-leaning independents is plus or minus 4.5 percentage points.
